Somfy TR4-DRM-230 DIN Rail Isolation Relay for 4 Drives, 230V AC, 4 Potential-Free Changeover Contacts, 5A 1822292

The Somfy TR4-DRM-230 is a DIN rail mounted isolation relay that cleanly separates the control side from four independent drive circuits. Unlike simple relay boards, it provides four potential-free changeover contacts, allowing you to switch low-voltage or mains loads without interference between channels.

Highlights

• Four independent channels, each with a potential-free changeover contact
• Designed for 230V AC control voltage, ideal for building automation
• Compact DIN rail housing for easy installation in distribution boards
• Screw terminals ensure secure and durable wiring

In daily use

This relay is typically used to isolate and switch motors, valves, or lighting circuits in smart home and industrial setups. Each contact is rated for 5 A at 250V AC or 30V DC, making it suitable for a wide range of loads. The low power consumption of approximately 3 VA keeps heat generation minimal.
